There are opposite numbers in VDI in the magnetic detector as well, but it does not have the main application according to the frequency current, and in magnetic detectors such as PULSE or VLF or TR and BFO metal detectors and IB metal detectors. ….. The answer and the answer of the opposite field in the reciprocal state like the main target field or gold or silver or desired metals is revealed in the magnetic current in the diffusion by changing the VDI number in the EDIT on the opposite numbers in his law The presence of pseudo-reflected fields of the main target cannot be separated by changing the opposite numbers in the VDI in order to make the separation correctly, because the detection classes in the magnetic detector in the lines of the reflection curve can detect the magnetic field emitted from the magnetic detector. changes in a state and the magnetizing wave loses its original composition in the conditions of changes in the diffuse magnetic field due to phase difference or field changes to pass or propagate again and does not return to the initial conditions of the diffuse magnetic field until GROUND BALANCE again or REST mode If the initial adjustment or start-up is done in the same settings again, as a result, it is not possible to isolate the difference between the fields that cause the error, and one of the factors is the lack of level and volume settings such as level and volume thresholds in the circuits of detectors or magnetic detectors or systems. are with magnetic waveforms
